f999c862ec libgo/testsuite: another fix for killing the sleep process
Avoid ps padding issues.  Make sure we locate and kill just the sleep
    process.

d0ceffe507 libgo/testsuite: don't call kill without args
If the timeout subshell has no child processes,
    the "xargs | kill" will fail. Ensure there is
    some input for kill before calling it.

1ca95ba067 syscall: RawSockaddr fix for ppc64, ppc64le
The struct RawSockaddr contains a field Data which
    should be uint8 on ppc64 and ppc64le, but is declared
    as int8 in gccgo.  This change adds a two new files
    which contain the structure declaration for
    RawSockaddr, one with the correct types for for ppc64
    and ppc64le, and the other for non-ppc64 platforms.

ca81dee392 libgo/testsuite: kill sleep process in gotest
This change modifies the "gotest" shell script
    to kill all processes, including "sleep", spawned
    by the timeout subshell. This prevents the sleep
    process from living beyond the gotest process.
    
    BACKGROUND
    
    The "gotest" shell script spawns "sleep" processes
    in the background to kill off test cases that run
    past their specified timeout. There are commands
    included that appear to kill the sleep process,
    but they only kill the parent shell, causing the
    sleep process to reparent.
    
    The orphaned sleep process can cause issues when
    gotest is run under some build systems, such as
    Ninja [0]. The particular issue with Ninja is the
    method it uses to identify terminated processes:
    it creates a pipe, passes the write end to the
    child process, and waits for EOF. In the case of
    libgo/gotest, the orphaned sleep process inherits
    the pipe FD and keeps it open for 4 minutes by
    default.

67a546ab45 compiler,runtime: Determine if allocations need new pointers in runtime.
As the removed comment states, if the package being compiled played
    certain tricks with pointers that looked like integers, the compiler
    might allocate space for new pointers unnecessarily.  Since the type
    information on the heap is now precise, this logic can be moved to the
    runtime.

GCC PR 65797 causes some of the runtime functions to be

There are no good choices when a function has no name in the

while reading the runtime functions, we assume that it is also
a runtime function.

9f5059b275 go/cmd/go: always link external test packages first
When linking complex packages that use both internal and external tests as well as many dependencies it is critical that the link order be external test package, internal test package, everything else.

This change is a back (forward?) port of the same change that canonical have been maintaining on their fork of the go tool for gccgo. Now that gccgo uses the go tool from upstream, this patch should be applied both to the gofrontend and golang/go repos.

runtime: Don't call malloc from __go_file_line callback.

When crashing, we call runtime_printcreatedby which calls
__go_file_line which used to call the Go malloc.  If we are
crashing due to a signal due to heap corruption of some sort,
the GO malloc lock might already be held, leading to a crash
within a crash.  Avoid that by assuming that the libbacktrace
strings will stick around, as we already do in go-callers.c.

898c81f831 mksysinfo.sh: Remove _zone_net_addr_t handling.
From Rainer Orth.

The recent godump changes broke Solaris 11.1+ bootstrap in
libgo: before, gen-sysinfo.so had

type _zone_net_addr_t struct { zna_family uint16; zna_plen uint16; zna_addru struct { znau_addr6 _in6_addr; }; }

which was filtered out by mksysinfo.sh due to the use of
_in6_addr.

After the change, there's now

type _zone_net_addr_t struct { zna_family uint16; zna_plen uint16; zna_addru struct { znau_addr6 [16]byte; Godump_0_align [0]uint32; }; }

instead, not filtered, but added a second time by the
_zone_net_addr_t code in mksysinfo.sh, which leads to
redefinition warnings/errors.

Simply removing the old _zone_net_addr_t fragment fixes this
and restores bootstrap.
